Description

The present invention relates to a roll material holder that holds a product (hereinafter referred to as a roll-shaped product) that is wound into a roll and cut and used as much as it is used, and is pulled out from a take-out portion as much as it is used and cut and used. More specifically, the present invention relates to an improvement of a take-out portion for pulling out and cutting out a roll-shaped product of a roll material holder by the amount used.

Conventionally, as a roll material holder that can be cut out with one hand and is arranged so as to be separated from the roll material main body so that the tip portion of the roll material after cutting can be easily pulled out at the next use, for example, there is one disclosed in Patent Document 1. ..

The roll paper holder described in Patent Document 1 is a first holder body composed of a back plate portion and left and right side plate portions, a roll support portion that rotatably supports the roll paper, and a first portion that presses the upper surface of the roll paper by a protrusion. It has a presser plate portion, a mounting rod portion on which the paper from the roll paper is placed, a second pressing plate portion that holds the paper on the mounting rod portion, and a front end portion of the second pressing plate portion. A receiving rod portion connected to and arranged in front of the mounting rod portion, a tip plate portion mounted on the receiving rod portion, and a holding portion that swingably holds the tip plate portion as a vertical swing fulcrum.

JP-A-2016-129957

However, in the apparatus described in Patent Document 1, the tip plate portion that presses the paper at the time of cutting is further in front of the mounting rod arranged in front of the roll material so that the tip portion of the roll material is separated from the roll material main body and can be easily pulled out. In addition, the tip plate part has a shaft on the back side, and in the case of uniform specific gravity, it is necessary to secure a front-rear length equal to or greater than the back side on the front side of the shaft, so the front side of the roll material Since it will overhang significantly, it is necessary to secure a sufficient space in the front direction of the roll material, and it is difficult to secure the compactness of the holder so that it can be installed even in a narrow space. In addition, if a large overhang from the back part causes a load to be applied from the upper part of the tip part by mistake, such as touching the upper surface of the tip plate part, a larger lever force will be applied to the main body. The risk of failure such as the main body falling off or the mounting wall surface being damaged increases. Moreover, a total of three rotation axes are required: the rotation axis used when cutting out the tip of the roll material, the rotation axis used to hold the tip at all times, and the rotation axis used when setting the roll material. The number of parts and the manufacturing process have increased, which is a factor in increasing costs. Furthermore, as a structure, the rotation shaft of the tip plate portion is not a structure that bridges the inside of the fixed side surface portion of the holder body, but is bridged between the inside of the side surface portion of the holder body, and itself swings on the rotation shaft. It is further bridged on the first holding plate. In other words, it has a nested structure in which the shaft-rotating parts are mounted on the shaft-rotating parts, and it is not easy to secure the strength and assembly accuracy of the parts and to reduce the cost accordingly.

That is, according to the structure of the roll paper holder described in Patent Document 1, the number of parts is large and the structure is complicated, and the structure that protrudes considerably in the front direction from the portion accommodating the roll material main body must be adopted. There is a problem that it becomes large and takes up a lot of space, and there is a greater risk of failure when a load is applied to the tip of the main body. Moreover, since the structure is complicated and the number of parts increases, not only the cost is high, but also it is fragile as a structural factor and requires complicated movements, which causes a problem that malfunctions and damages are likely to occur. Includes.

An object of the present invention is to provide a roll material holder which has a simple and compact structure and can be easily operated with one hand.

In order to achieve such an object, the roll material holder according to claim 1 holds a roll material that is wound into a roll and cut and used as much as it is used, and is pulled out from a take-out part as much as it is used and cut and used. In the holder, a roll material support shaft that engages with the central cavity of the roll material to rotatably support the roll material body, a blade for cutting out the portion to be used from the portion drawn out from the roll material body, and the roll material. A flap and roll material that are rotatably supported around a rotation axis parallel to the support axis, have a center of gravity behind the rotation axis, and are constantly urged to rotate in one direction by their own weight. The part pulled out from the roll material body is placed, and it is equipped with a flap receiver that is sandwiched between the flap and the flap, and the flap is pressed against the flap receiver by the cut-out part of the roll material drawn from the gap between the flap holder. When it is pressed against the end opposite to the end to be pressed and pulled toward the blade, it rotates toward the flap receiver and is fixed by sandwiching the part pulled out from the roll material body with the flap receiver. However, the roll material is cut by hitting the blade with tension applied to the pulled-out part.

Further, the roll material holder according to the second aspect of the present invention has a rotating shaft at the rear end portion, swings around the rotating shaft, directly contacts the roll material main body, and reversely rotates the roll material main body. It is equipped with a movable roll material body retainer that prevents the roll material from being pressed, and the edge around the rotation axis of the roll material body retainer functions as a flap receiver, while the outer surface of the roll material body retainer is pulled out from the roll material body. It is designed to function as an uncut part receiving part that supports and supports the uncut part between the part sandwiched between the flap of the flap and the flap receiver and the blade.

Further, in the roll material holder according to the invention of claim 3, the portion of the flap and the flap receiver in contact with each other has an uneven shape, and the concave-convex shape is fitted when the roll material is cut out, and the flap and the flap receiver are separated from each other. The portion drawn out from the passing roll material body is sandwiched between the uneven shapes.

Further, in the roll material holder according to the invention of claim 4, the flap is made to shield the upper part of the roll material main body.

Further, the roll material holder according to the fifth aspect of the invention supports the curved plate-shaped saucer portion and both ends of the saucer portion so as to rotatably support the saucer portion around the roll material support shaft of the holder body. It has a pair of left and right arm parts, and is equipped with a roll material saucer in which the rotation of the saucer is fixed under the flap, and the part where the outer surface of the saucer is pulled out from the roll material body of the roll material is with the flap. It functions as a flap receiver that is sandwiched between the flap receivers and an uncut portion that supports and supports the uncut portion drawn from the roll material between the flap receiver and the blade, and rotates around the roll material support shaft when the roll material is replaced. By doing so, the saucer portion is hung from the roll material support shaft, and the inner surface of the saucer portion functions as a temporary storage portion for the roll material to assist the roll material replacement work.

Further, the roll material holder is provided with a flap and a flap receiver under the roll material, and a blade is provided at the tip of the flap.

Here, it is preferable to provide a through hole into which a finger can be inserted in the vicinity of the flap blade.

Further, under the flap and on the portion of the roll material pulled out from the roll material main body, the roll material is separated from the flap by rotation by its own weight about the rotation axis and passes between the flap and the flap receiver. The roll material holder according to claim 6, further comprising a peeling flap for peeling a portion of the roll material drawn from the roll material main body from the blade.

Further, the blade is attached to a rotating body having an eccentric center of gravity provided at the tip of the flap, and when the roll material is pulled out, the rotating body rotates together with the roll material and the blade protrudes on the moving locus where the roll material is pulled out. The roll material is separated while the rotating body is fixed by a stopper provided between the flap and the flap, and after the separation, it is preferable that the rotating body is retracted from the movement locus of the roll material by moving the center of gravity of the rotating body.

Further, it is preferable that the blade has a portion having low friction and a portion having high friction, the tip side of the blade has high friction, the proximal end side has low friction, and the width of the proximal end side is wider than that of the distal end side.

According to the roll material holder according to claim 1, the uncut portion of the roll material pulled out from the gap between the flap and the flap receiver is pressed against the end portion opposite to the end portion pressed against the flap receiver. When it is pulled toward the blade, it rotates toward the flap holder, sandwiches and fixes the part pulled out from the roll material body with the flap holder, and applies tension to the pulled out part of the roll material. Since it is cut by hitting it against the blade in the state of being cut, the roll material can be pulled out and cut as much as it can be used with one hand, and the structure is simple and compact. Moreover, parts such as flaps can be attached and detached because the tip of the roll material can be set in the gap between the flap holder and the flap holder, which is created by rotating the flap in the opposite direction, by simply dropping the tip of the roll material from top to bottom. It can be easily operated with one hand. Further, the uncut portion of the roll material sandwiched between the flap and the flap receiver is constantly pressed against the flap receiver by the rotational force due to the flap's own weight and is sandwiched, so that the uncut portion is moved to the roll material main body side. It is possible to prevent it from being pulled back, and the uncut portion exists in a fixed position in a state of being separated from the roll material body, and the tip portion can be easily pulled out with one hand even at the next use.

Further, according to the invention of claim 2, since the structure can be made simple and compact by using the flap receiver, the uncut portion receiving portion, and the roll material main body retainer in one part, the number of parts is not increased. It is possible to prevent the reverse rotation of the roll material body and prevent the uncut portion of the roll material from being pulled back, which makes it easier to pull out and cut the roll material next time. Moreover, since the uncut portion of the roll material is supported by the uncut portion receiving portion on the outer surface of the roll material main body retainer, the uncut portion can be easily picked while being pressed against the uncut portion receiving portion.

Further, according to the invention of claim 3, when the roll material is cut out, the unevenness of the flap and the flap receiver is fitted, so that the portion of the roll material pulled out from the roll material main body is the flap and the flap receiver. The force to pinch between the rolls is increased to fix the roll material, and even after cutting, the uncut part of the roll material due to the increase in frictional force due to uneven fitting prevents the roll material body from pulling back at the tip more firmly. Can be done. It is possible to enhance the strength of the presser foot and the function of suppressing the reverse rotation of the roll after cutting.

Further, according to the invention of claim 4, the flap covers the main body of the roll material, protects the roll material from water droplets and dust from above, and can contribute to maintaining hygiene of the roll material.

Further, according to the invention of claim 5, the roll material is passed through the roll material support shaft, placed on the saucer portion of the roll material saucer, the tip side is pulled out and hung down on the front side of the saucer portion, and then the roll material is hung. By simply rotating the saucer to the used position, the roll material can be set on the holder body with the uncut portion pulled out from between the flap receiver and the flap. Therefore, the roll material can be set on the holder body very easily. Moreover, the roll holder can be made compact without impairing the operability when the roll material is attached.

Further, according to the roll material holder according to claim 6, the holder size can be made compact. In addition, the procedure for setting the portion of the roll material pulled out from the roll material body between the flap and the flap receiver can be simplified.

Further, according to the roll material holder according to claims 7 and 8, even if the hangnail at the tip edge of the uncut portion adheres to the blade, it can be forcibly peeled from the tooth by sticking with a finger or lowering the peeling flap. , Does not cause the problem that the uncut part does not hang down.

Further, according to the roll material holder according to claim 9, since the blade is projected only when it is needed, it is possible to reduce the influence of fear and the like caused by the blade being always exposed.

Further, according to the roll material holder according to claim 10, since the tip side of the blade has high friction, the base end side has low friction, and the width of the base end side is wider than that of the tip end side, the blade prevents forward slippage. It acts easily to bite into the blade, and it does not get caught because it has a larger gap than the tip side where friction is large and it is easy to come off. That is, it is possible to achieve both good bite when pressing the cut-out portion of the roll material and easy separation of the uncut portion after cutting, and promote peeling of the uncut portion attached to the blade. As a result, a part of the roll material is separated, and at the same time, the uncut portion hangs down due to free fall.

Hereinafter, the configuration of the present invention will be described in detail based on the embodiments shown in the drawings. In the present specification, the three axial directions of the front-rear direction (Y-axis), the left-right direction (X-axis), and the vertical direction (Z-axis), which are orthogonal to each other, are defined as the vertical direction (Z-axis) unless otherwise specified. The front side or the outside means the left side of the reference in FIGS. 1 and 2, and the back side or the inside means the right side of the reference in FIGS. 1 and 2.

1 and 2 show an example of an embodiment of the roll material holder of the present invention. The roll material holder according to this embodiment is applied to a toilet paper holder, and the toilet paper wound in a roll shape (hereinafter referred to as a roll material 1; in particular, a portion wound in a roll shape is a roll material. It has a holder main body 4 that rotatably holds the main body 1a), a flap 6 that enables cutting of the roll material 1, and a flap receiver 7, and is used from the roll material main body 1a held by the holder main body 4. It is designed to be pulled out and cut out for use. The holder body 4 of the present embodiment is used by being attached to a wall surface of a structure or the like.

The holder body 4 is a plan-view U-shaped frame composed of, for example, a back member 2 attached to a structure, a wall surface, or the like, and left and right side members 3 extending forward from both left and right ends of the back member 2 and facing each other. The roll material support shaft 5 is provided so as to stand inward from the side surface member 3 so as to be perpendicular to the side surface member 3 (parallel to the back surface member 2), for example. The roll material support shaft 5 rotatably supports the roll material by being inserted into the central cavity 1c of the roll material body 1a. For example, the roll material body 1a is placed below the inner space of the holder body 4. When inserting from, it is pushed down by the roll material body 1a to allow the roll material body 1a to pass through, and when the roll material body 1a is completely contained in the internal space of the holder body 4, it automatically stands up by the force of the built-in spring. It is a shaft capable of swinging motion that jumps into the central cavity portion 1c of the roll material main body 1a.

The holder main body 4 has a flap receiver 7 on which a portion peeled out from the roll material main body 1a or a portion left uncut (hereinafter, these are collectively referred to as an uncut portion 1b) and a flap receiver 7 are placed. With a flap 6 that is always pressed by its own weight and sandwiches the uncut portion 1b between the flap receiver 7 and the flap receiver 7, the uncut portion 1b is pulled out from the gap between the flap 6 and the flap receiver 7. It is provided. In the present embodiment, a flap 6 and a flap receiver 7 serving as a take-out portion are provided on the upper front side of the holder main body 4.

In the case of the present embodiment, the flap 6 is made of, for example, a rectangular flat plate in a plan view as shown in FIG. 2, and the acute-angled tip edge also serves as the blade 9, so that the roll material 1 can be cut off. In the case of the present embodiment, the flap 6 is horizontally arranged in the space between the left and right side surface members 3 of the holder body 4, and is parallel to the roll material support shaft 5 (in other words, the rotation center of the roll material body 1a). It is rotatably supported around a rotating shaft (hereinafter referred to as a flap shaft 6a). The flap 6 is arranged at a position where it does not interfere with the roll material main body 1a housed in the internal space of the holder main body 4 and at a position where the tip end portion of the roll material main body 1a can be easily taken out. For example, in the case of the present embodiment, as shown in FIG. 1, the flap 6 is a roll material on the front side of the roll material support shaft 5 and above the roll material main body 1a supported by the roll material support shaft 5. It is provided at a position that does not interfere with the main body 1a.

Here, the arrangement interval between the flap receiver 7 and the flap 6 is, for example, an interval such that at least a gap is formed between the flap shaft 6a and the flap receiver 7 to pull out the tip of the roll material, that is, the uncut portion 1b, preferably used. A space is provided so that a person's fingertip can be freely inserted, and when the flap 6 is pressed against the flap receiver 7, the uncut portion 1b is sandwiched between the flap 6 and the flap receiver 7 to fix and roll. It has a positional relationship that makes it possible to prevent the material from feeding out or reversing, and is provided so that the uncut portion 1b is always pressed from above by its own weight with the flap 6 in a state where it is placed on the flap receiver 7. .. That is, the center of gravity of the flap 6 is set behind the flap shaft 6a, and the flap 6 can rotate to the holder body 4 so that the force of rotating the flap 6 in one direction, that is, toward the flap receiver 7 is always urged by its own weight. It is supported. Then, the tip portion pulled out from the roll material main body is taken out from the gap between the flap 6 and the flap receiver 7.

The flap 6 is integrally provided with flap shafts 6a projecting in the width direction (X-axis direction in FIG. 2) on both side surfaces facing the side surface members 3 of the holder body 4, and the left and right side surface members 3 of the holder body 4 are integrally provided. The flap shafts 6a on both sides are fitted into the bearing recesses, for example, the bearing grooves 8 provided in the respective bearing grooves 8 to be rotatably supported. Of course, the flap shaft 6a may be a shaft separate from the flap 6, for example, one rotating shaft penetrating the flap 6 in the width direction, and the bearing grooves 8 of the left and right side surface members 3 and 3 of the holder body 4 may be used. The flap 6 is rotatably supported by being fitted into the flap 6. The bearing groove 8 accommodating the flap shaft 6a has, for example, a round hole having a size for rotatably supporting the flap shaft 6a, a triangular long groove in which the flap shaft 6a can be easily moved, and a constricted portion. , The flap shaft 6a inserted into the long groove is supported by the round hole portion by passing through the constricted portion.

In the case of the present embodiment, the blade 9 is formed by the acute-angled edges of the flap 6, but is not particularly limited to this. For example, as shown in FIG. 5, the blade 9 projects downward so as to be orthogonal to the flap 6. It may be formed by (burr) -shaped edges. It is preferable to project the blade 9 downward because there is little escape (slip) when cutting the portion pulled out from the roll material main body 1a, and the blade 9 can be cut with a light force. Further, the blade 9 may be formed so as to project upward or forward as shown in FIG. 13, and in some cases, the blade 9 is separated from the tip edge of the flap 6 on the back side and on the front side of the flap shaft 6a. It may be formed so as to protrude from the lower surface of the flap. Further, the blade 9 is not limited to the one formed integrally with the flap 6, and the blade 9 formed separately is formed into a saw blade shape with a soft resin such as EVA resin (ethylene / vinyl acetate copolymer resin). The formed separate parts may be fixed to the flap 6 by adhesion or welding.

Further, as shown in FIG. 10, the blade 9 formed separately from the flap 6 may be provided on the side of the roll material holder 4 and arranged in front of the flap 6 (front side). good. For example, the blade 9 of another part may be installed and fixed so as to straddle between the side walls 3 of the roll material holder 4. In this case, the blade 9 of the separate part may be always exposed, but it may be movable so that the blade 9 is relatively exposed when the portion drawn out from the roll material main body 1a is pressed against it.

In the case of the present embodiment, the flap 6 is formed in a flat plate shape as a whole, but is not particularly limited to this. For example, although not shown, the region on the front side of the flap shaft 6a faces downward. It may be curved. In this case, the blade 9 formed on the tip edge of the flap 6 faces downward, making it difficult for the user to see, and the fear and anxiety about the blade 9 can be alleviated. Even if the blade is safe, there are many people who feel the psychological fear and discomfort of touching the blade, and many who show rejection of the blade protruding toward the front. This is preferable as a consideration for such users. Further, it is possible to eliminate the escape (slip) when separating the portion pulled out from the roll material main body 1a so that the force can be easily applied at a right angle and to cut with a light force.

The flap receiver 7 sandwiches the uncut portion 1b between the flap receiver 7 and the flap 6 only by the pressing force due to the weight of the flap 6 during standby when the roll material is not cut, and the flap 6 is on the front side centering on the flap shaft 6a at the time of cutting. By rotating the (tip edge side) in the lifting direction (clockwise rotation direction in FIG. 1), the uncut portion 1b is sandwiched between the flap 6 and the flap 6 more strongly than in the standby state. That is, when cutting the roll material, it is necessary to fix the uncut portion 1b, and at other times, it is preferable to provide a slight frictional resistance that can prevent the uncut portion 1b from being unwound. Therefore, the flap receiver 7 sandwiches and fixes the uncut portion 1b with the flap 6, and when the uncut portion 1b is applied to the blade 9 and pulled to be separated, the roll material 1 to be pulled out. It is intended to prevent the feeding or reversion of the sword so that tension is applied. Then, during standby after cutting the roll material, the flap 6 functions to prevent the uncut portion 1b from reverting due to its own weight.

Here, the flap receiver 7 is a fixed plate having a ridge line portion (contact portion 11) as shown in FIG. 4 even in the shaft member as shown in FIG. 1, considering only the function as a receiver of the flap 6. It is not inferior to any of the shaped members or any method. On the other hand, in the case of the axial flap receiver 7 as shown in FIG. 1, the uncut portion 1b between the blade 9 and the flap receiver 7 is the contact position between the flap 6 and the flap receiver 7 deeper than the blade 9. (That is, it hangs down near the position where the uncut portion 1b is sandwiched). On the other hand, as shown in FIG. 4, in the case of the plate-shaped flap receiver 7, the uncut portion 1b is an inclined surface (hereinafter, uncut receiver) on the front side of the contact position between the flap 6 and the flap receiver 7. By being supported on the portion 10), the uncut portion 1b can be picked on the front side as compared with the case of the shaft-shaped flap receiver 7. Moreover, since the uncut portion 1b can be picked up while being pressed against the uncut receiving portion 10, it becomes easy to pick. That is, from the viewpoint of ease of grasping the uncut portion 1b, the plate-shaped flap receiver 7 as shown in FIG. 4 in which the uncut receiving portion 10 exists on the front side of the contact position between the flap 6 and the flap receiver 7. Is preferable. The flap receiver 7 in this case is, for example, a metal plate or a resin plate bent in a substantially chevron shape, and is provided so as to sandwich the uncut portion 1b with the bent point (ridge line) portion as the contact portion 11 with respect to the flap 6. There is. Since the plate-shaped flap receiver 7 is not particularly required on the back side of the contact portion 11 with respect to the flap 6, for example, the uppermost portion of the rear end of the inclined plate is set as the contact portion 11 with respect to the flap, and the front side thereof is left uncut. It may be made to function as a receiving part 10. The plate-shaped flap receiver 7 is fixed to both side surface members 3 of the holder main body 4, and its inclination does not change. Regardless of whether it is rod-shaped or plate-shaped, the flap receiver 7 is attached to the lower surface of the flap 6 attached to the upper front portion of the holder body 4 on the back side of the flap shaft 6a at a position where the flap 6 can be prevented from rotating. Has been done.

Here, the position of the flap shaft 6a may be on the front side of the center of gravity of the flap 6 and on the back side of the front end (outer end) of the flap 6, and is limited to a specific position. Absent. For example, in the embodiment of FIG. 1, the flap shaft 6a is provided on the front side from the center (center of gravity position) of the length in the front-rear direction of the flap 6 so that the center of gravity position is arranged on the back side of the flap shaft 6a. However, if a weight or the like is built in, the position of the center of gravity can be easily changed, so that the position of the rotating shaft 6a is not limited to the length of the flap in the front-rear direction. That is, if the flap 6 has a uniform wall thickness and specific gravity with the center of gravity at the center, the flap shaft 6a is provided on the front side of the flap 6 as much as possible from the center of the front-rear length so that the center of gravity is on the back side. However, if the center of gravity itself is located behind the center of the front-rear length of the flap 6, the flap shaft 6a may be provided behind the center of the front-rear length of the flap 6. Further, in some cases, the center of gravity of the flap 6 may be provided on the back side of the flap receiver 7. As a result, the flap 6 can be rotated about the flap shaft 6a toward the side having the center of gravity so as to be constantly tilted by its own weight, and the flap 6 can be pressed against the flap receiver 7.

Of course, if the flap shaft 6a is provided as close to the front edge of the flap 6 as possible, that is, the tip edge, the flap shaft 6a and the back side of the flap are supported while keeping the volume of the roll material holder body 4 compact. Since the distance between the flap receiver 7 and the flap receiver 7 can be increased, it becomes easy for the tip of the uncut portion 1b to pass through the gap between the flap shaft 6a and the flap receiver 7. That is, the setting work of the tip portion of the roll material can be performed more easily with one hand. Therefore, it is preferable that the flap shaft 6a is provided on the front side of the flap 6, that is, at a position closer to the tip edge as much as possible.

On the other hand, the position of the flap receiver 7 is the position where the uncut portion 1b of the roll material hangs down, or the start position of the uncut receiving portion 10. Therefore, considering the next cutting work and the like, the true position of the roll material support shaft 5 It is preferable to prepare near the top.

Further, in the case of the present embodiment, the flap 6 and the flap receiver 7 are provided with the flap shaft 6a and the flap receiver 7 at substantially the same height so that the flap 6 is kept horizontal. It is not limited. Although it is an extreme example, the flap receiver 7 may be arranged above the flap shaft 6a, for example, as shown in FIG. That is, the flap shaft 6a is arranged on the front side of the flap receiver 7, and the center of gravity of the flap is arranged on the back side of the flap shaft 6a, so that the flap 6 is constantly pressed against the flap receiver 7. It suffices if the force to be generated is in a relationship generated by its own weight.

If the flap 6 is a flat plate as shown in FIGS. 1 and 2, the flap receiver 7 is arranged obliquely with respect to the roll material pull-out direction on the XY plane, and the flap 6 and the flap receiver 7 come into contact with each other. Even if the portion 11 (the line that sandwiches the uncut portion 1b) becomes non-parallel to the flap shaft 6a, there is no significant difference in the function of sandwiching the uncut portion 1b. However, in this case, since the portion drawn out from the roll material main body 1a hangs down as the uncut portion 1b along the contact portion 11, the uncut portion 1b may not face straight ahead. In other words, in order for the uncut portion 1b that hangs down along the contact portion 11 to face directly in front, it is preferable that the flap shaft 6a and the flap receiver 7 are provided so as to maintain a substantially parallel relationship. .. Further, regarding the relationship between the flap axis (fulcrum) 6a and the flap receiver (point of action) 7, ensuring parallelism in both the XY plane and the XY plane is directly linked to the improvement of sharpness.

In the case of the present embodiment, the portion of the flap receiver 7 that comes into contact with the flap 6, that is, the contact portion 11, is in any case when a shaft is used as the flap receiver 7 or when a ridgeline of a plate bent into a chevron shape is used. Is also configured as a "line" that crosses the holder body, but in some cases it may be a surface. For example, when the flap receiver 7 of the plate bent into a chevron shape as shown in FIG. 4 is adopted, the contact area may be increased by making the ridge line portion (contact portion 11) a gentle curved surface having a large radius of curvature. By adopting the trapezoidal flap receiver 7 as shown in FIG. 12, the flat contact portion 11 may be formed. In this case, since the frictional resistance when pulling out the portion to be cut out from the roll material main body 1a is increased as compared with the case of the shaft-shaped flap receiver 7, the roll material main body 1a is less likely to idle due to the inertial force and to be extended excessively. On the other hand, if the frictional resistance increases too much, it becomes easy to tear when the roll material is pulled out, so that the contact between the flap 6 and the flap receiver (shaft or plate) 7 is larger than when the cut portion is pulled out from the roll material body 1a. It is preferable that the frictional resistance is low and the frictional resistance is higher when cutting than when pulling out.

According to the roll material holder of the present embodiment configured as described above, the roll material replacement work can be easily performed without removing the flap 6 and / or the flap receiver 7 from the holder main body 4. For example, as shown in FIG. 3A, when the flap 6 is turned to the front side (for example, 270 ° counterclockwise rotation) and the back side of the flap 6 is hung down, the flap receiver 7 and the flap are flapped. Since a gap is generated between the shaft 6a and the flap 6, the portion drawn out from the roll material main body 1a can be passed through the gap and hung down. After that, when the flap 6 is rotated forward (rotated by 270 ° in the clockwise direction), the rear end (back) side of the flap 6 is placed on the flap receiver 7 and returned to the horizontal position, the space between the flap 6 and the flap receiver 7 is reached. The portion pulled out from the roll material body 1a with the tip end portion of the roll material sandwiched between the two hangs down to the front side of the flap receiver 7 as an uncut portion 1b. The work of setting the roll material on the holder body 4 can be easily performed with one hand.

Then, when the uncut portion 1b hanging down to the front side of the flap receiver 7 is picked and pulled toward the front side (horizontal direction or diagonally downward direction), the back side of the flap 6 becomes the flap receiver 7 due to the weight of the flap 6. The required amount can be smoothly pulled out from the roll material body 1a with one hand without exerting more force than the pressing force.

When the required amount can be pulled out from the roll material main body 1a, the pulled-out portion is lifted upward, and in the case of the embodiment shown in FIG. 1, the flap 6 rotates in the clockwise direction and the end on the back side of the flap 6. The portion is further pressed against the flap receiver 7. As a result, the uncut portion 1b is sandwiched and fixed between the flap 6 and the flap receiver 7, and the uncut portion 1b cannot move back and forth.

If the uncut portion 1b is further pulled upward in this state, tension is applied to the uncut portion 1b on the front side of the portion sandwiched between the flap 6 and the flap receiver 7, and the uncut portion 1b is separated by the blade 9. .. As a result, it can be cut out reliably and easily with one hand.

When the cutting is completed, the uncut portion 1b between the blade 9 and the flap receiver 7 is sandwiched between the flap receiver 7 and the flap receiver 7 by its own weight, so that it may be rewound due to recoil during cutting. It is suppressed and is not rewound to the roll material body 1a side. Therefore, since the uncut portion 1b beyond the portion sandwiched between the flap receiver 7 and the flap 6 surely hangs down from the flap receiver 7, the uncut portion 1b can be easily picked up and pulled out at the next use. Is easy to pull out. Further, when the flap receiver 7 is formed in a plate shape as shown in FIG. 4 (or in the case of the roll material main body retainer 14 of the embodiment shown in FIGS. 5 and 6), the contact portion (or the contact portion in contact with the flap 6) Since the uncut portion 1b is received and supported by the slope on the front side of the line portion) 11, that is, the uncut receiving portion 10, the uncut portion 1b is easily picked by pressing a finger against the uncut receiving portion 10. be able to. Therefore, the work of peeling and pulling out the uncut portion 1b from the roll material body 1a without finding it does not cause stress.

Thus, one-handed operation is possible over the entire process, from setting the roll material to cutting operation. Moreover, the roll material can be easily set without removing the parts. Furthermore, it is hygienic because it is possible to cut out the roll material without touching any unused parts other than the part to be cut out.

According to the roll material holder of the present embodiment configured as described above, the structure is as simple as assembling so that the two points of the flap 6 and the flap receiver 7 are hung between the left and right side surface members 3 of the holder body 4. Therefore, it can be carried out without significantly changing the manufacturing process of existing roll material holders such as toilet paper holders and the strength and accuracy required for each part, and inexpensive and robust holders can be easily manufactured. .. Moreover, since the take-out part can be configured only with the flap 6 and the flap receiver 7, compactness can be realized without taking up space, a simple structure with a small number of parts can be realized, and robust, easy and inexpensive manufacturing is possible. Become.

Further, it is not necessary to add a new shaft function for pulling the flap shaft 6a and the flap receiver 7 apart in order to set the roll-shaped main body 1a, and the flap shaft 6a is also used as a shaft function for roll setting, and the member is removed. Even if a set shaft is not provided, a portion drawn out from the roll material main body 1a can be easily set between the flap shaft 6a and the flap receiver 7. Therefore, it is possible to design compactly and achieve both low-cost production such as reduction of the number of parts. Further, the arrangement interval between the flap receiver 7 and the flap 6 is such that at least a gap for pulling out the tip of the roll material is formed between the flap shaft 6a and the flap receiver 7, preferably, the user's fingertip is freely inserted. It suffices if there is an interval that allows it to be inserted, and the length from the flap shaft 6a to the front end can also be shortened, so that a large overhang in the front direction of the holder body 4 can be suppressed. Be done. Moreover, since the flap hardly rotates in the vertical direction and the posture does not change, no special space for rotation is required in the vertical direction. From this, since the mechanism of the take-out part by the flap 6 and the flap receiver 7 can be designed compactly, the fit in the narrow toilet private room space can be suppressed to the same level as the existing general holder.

Since this roll material holder has a constant cutting position, it is not affected by changes in the remaining amount (roll diameter) of the roll material body 1a, and even if the remaining amount of the roll material body 1a is low, that is, winding. Even if the diameter is small, stable cutting can be performed and the sharpness is always constant, which is excellent in usability. Moreover, since the flap 6 is installed above the roll material main body 1a, the uncut portion 1b can be easily visually recognized.

5 and 6 show still other embodiments. The roll material holder according to this embodiment includes a movable roll material main body retainer 14 that comes into direct contact with the roll material main body 1a and constantly presses the roll material main body 1a to prevent reverse rotation. The roll material main body retainer 14 of the present embodiment is not only as a means for preventing the roll material main body 1a from rotating in the reverse direction and unwinding the uncut portion 1b, but also as a flap receiver 7 and an uncut receiving portion 10. It also serves as. That is, the cylindrical portion surrounding the rotating shaft 15 of the roll material main body retainer 14 is used as the flap receiver 7, while the outer peripheral surface of the roll material main body retainer 14 is used as the uncut receiving portion 10.

The roll material body presser 14 of the present embodiment is always in contact with the outer peripheral surface of the roll material body 1a at the tip edge portion and is pressed by its own weight, but the present invention is not particularly limited to this, and the tip edge edge is as shown in FIG. The portion 19 may be rolled and rolled (curling) so that the portion 19 can be pressed at a portion other than the tip edge portion 19. That is, it is not limited to the tip edge portion 19, but is always in contact with any region on the back surface of the uncut receiving portion 10, or, although not shown, the uncut receiving portion 10 is warped with respect to the roll material body 1a in the opposite direction. May be curved. In this case as well, as the diameter of the roll material body 1a changes, the contacted portion shifts, so that the roll material body 1a is always in contact. As a result, the uncut portion 1b and the portion of the roll material main body 1a are pressed at the same time, which effectively functions to prevent the roll material main body 1a from reversing.

In the case of the present embodiment, the roll material body retainer 14 is formed by a rotating shaft 15 penetrating a cylindrical portion 17 that also functions as a flap receiver 7 at the base end portion of the roll material body retainer 14, as shown in FIG. It is rotatably supported by the bearing grooves 8 of the left and right side wall members 3. However, the support structure is not particularly limited, and in some cases, the support may be rotatably supported by a shaft integrally formed with the roll material main body retainer 14. Needless to say, it is preferable in terms of configuration that the shaft as the flap receiver 7 and the rotating shaft of the roll material main body retainer 14 are used in combination because the number of parts is reduced and the structure can be simplified.

The roll material main body retainer 14 of the present embodiment is formed, for example, in the shape of a curved plate along the curved surface of the roll material main body 1a. That is, the larger the diameter of the roll material body 1a, the stronger the force to rewind the uncut portion 1b due to the reversal due to the recoil at the time of cutting, so that the importance of preventing the roll material body 1a from reversing becomes higher. .. Therefore, it is preferable that the roll material main body retainer 14 has a curved surface having substantially the same curvature and radius of curvature as the curved surface of the roll material main body 1a at the maximum diameter.

On the other hand, as the remaining amount of the roll material body 1a decreases, the reversing force of the roll material body 1a also becomes weaker accordingly, and the importance of the contact of the roll material body retainer 14 with the roll material body 1a decreases. Moreover, if the roll material body presser 14 continues to be in contact with the roll material body 1a even if the diameter of the roll material body 1a becomes smaller, the roll material body presser 14 becomes more inclined and approaches a hanging state. Therefore, on the contrary, it becomes difficult to remove the uncut portion 1b. Further, if the roll material main body retainer 14 hangs vertically, for example, when trying to attach a new roll material 1 from below, if the roll material main body retainer 14 is not lifted, it will be struck, so the roll material 1 can be set with one hand. Get in the way of. Therefore, at a position or angle at which the presser foot for preventing the roll material body 1a from reversing is unnecessary or ineffective, a stopper member, for example, a protrusion (not shown) that prevents the roll material body presser 14 from further tilting or hanging is left and right. The structure may be such that the roll material main body retainer 14 is stopped from moving by being provided on the inner surface of at least one or both of the side member 3 or the inner surface of the back member 2. For example, when the inclination of the roll material main body retainer 14 becomes an angle suitable for picking the uncut portion 1b, for example, about 45 degrees, the remaining amount of the roll material main body 1a is low and the reversing force is weak. Since the importance of contact with the roll material main body 1a is reduced, a structure may be provided in which a protrusion or the like (not shown) is provided on the inner wall surface of the side surface member 3 to stop the further inclination of the roll material main body retainer 14.

Further, by providing a female-type and male-type fitting structure at the contact portion 11 between the flap 6 and the flap receiver 7, the effect of holding down the uncut portion 1b and suppressing rewinding to the roll material main body 1a side is further enhanced. Can be enhanced. For example, as shown in FIG. 7, while the flap receiving 7 side has a shaft structure (cylindrical portion 17), a semicircular groove (arc) that is convex upward at a portion near the rear end side of the flap 6 that abuts on the shaft structure. As the portion 16), the curved surface of the cylindrical portion 17 and the curved surface of the arc portion 16 may be fitted to each other to form a fitting portion 18 that sandwiches the pulled-out portion of the roll material. That is, since the contact portion 11 between the flap 6 and the flap receiver 7 comes into contact with the surface contact or an approximation thereof, the contact area becomes larger than in the case of the line contact shown in FIG. 1, and therefore the roll material main body 1a It is possible to increase the holding force of the portion drawn from. That is, when cutting the roll material, the arc portion 16 of the flap 6 is pressed onto the cylindrical portion 17 that functions as the flap receiver 7 of the roll material main body retainer 14, and the uncut portion 1b is sandwiched in a wide area during standby. Rewinding and pulling out of the uncut portion 1b are more reliably suppressed. Further, when the roll material is pulled out, tension is applied to the uncut portion 1b, so that the trajectory of the outer peripheral portion of the roll material tries to draw the shortest route passing through the crown portion of the cylindrical portion 17, so that the flap 6 is formed by the uncut portion 1b. Both ends of the arc portion 16 of the above are pushed up, the fitting is released, and the gap is widened. Therefore, an excessive frictional force is not applied to the uncut portion 1b. Then, at the time of cutting, the arc portion 16 is pressed against the cylindrical portion 17 to be fitted by receiving an external force at the time of cutting (that is, a force for lifting the flap tip), so that the arc portion 16 is cut between the cylindrical portion 17 and the arc portion 16. The remaining portion 1b is sandwiched and fixed.

15 to 17 show still other embodiments. The roll material holder according to this embodiment incorporates a roll material tray 20 that also serves as an uncut receiving portion 10 and a flap receiver 7. That is, in the roll material holder of this embodiment, at the use position (see FIG. 17), the back side of the outer surface 28 (the portion where the end portion on the back side of the flap 6 hits) is the flap receiver 7, and the front side is the uncut receiver. A roll material tray 20 which is used as a portion 10 and whose inner surface 27 is used as a saucer on which the roll material is placed and supported at the exchange position (see FIG. 16) is provided.

As shown in FIG. 15, for example, in the roll material tray 20, the outer surface 28 functions as the flap receiver 7 and the uncut receiving portion 10, while the inner surface 27 functions as the temporary placement portion of the roll material 1. It is composed of 22 and a pair of left and right arm portions 21 that support both ends of the saucer portion 22 and rotatably support the saucer portion 22 around the roll material support shaft 5 of the holder body 4.

In the case of the present embodiment, the saucer portion 22 has an arc shape forming a part of a cylinder, and is formed, for example, on a curved plate (hereinafter, referred to as a curved plate) along the curved surface at the maximum diameter of the roll material main body 1a. ing. The saucer portion 22 exhibits a saucer function of receiving the roll material at the exchange position shown in FIG. 16 and assisting the roll material exchange work, and at the use position, the uncut portion 1b can be sandwiched between the flap 6 and the flap 6. That is, it is sufficient if the portion (contact portion 11) that comes into contact with the flap 6 as the flap receiver 7 can achieve a degree of adhesion capable of sandwiching the pulled-out portion of the roll material. Therefore, the saucer portion 22 is preferably an arc surface, but is not particularly limited to this, and may have a polygonal shape, for example.

Further, since the saucer portion 22 functions as a temporary storage portion for the roll material at the replacement position, if the central angle of the arc is too large, it interferes with the insertion of the roll material, and if it is too narrow, the flap receiver 7 and the uncut portion are left uncut at the use position. Since the length is insufficient when used as the receiving portion 10, the length is in the range of about 60 ° to 180 °, preferably 70 ° to 150 °, more preferably 80 ° to 130 °, and further preferably 90 ° to 120. The arc is inferior to about °. For example, in the case of this embodiment, it is set to 120 °, but the arc is not particularly limited to this.

In the case of the present embodiment, the disk-shaped arm portion 21 has a hole 23 that is slightly larger than the roll material support shaft 5 at the center, and an arc-shaped guide groove 24 and a locking for positioning around the hole 23. A hole 25 is provided so that the claw portion 26 protruding from the side member 3 of the holder body 4 together with the roll material support shaft 5 engages with either the guide groove 24 or the lock hole 25. The claw portion 26 is provided so as to fix the arm portion 21 at a predetermined position by engaging with the locking hole 25 and not to rotate unless an external force is applied. That is, it prevents the roll material tray 20 from rotating due to its own weight. The roll material tray 20 fixes the arm portion 21 by being provided so that the claw portion 26 and the locking hole 25 engage with each other at a position where the center of gravity is arranged on the upper side of the rotation center axis and on the front side. ing. Here, when the saucer portion 22 and the arm portion 21 are integrally molded with a synthetic resin, the effect of shifting the position of the center of gravity from the vertical line may not be clear because of its light weight. In such a case, in order to set the center of gravity closer to the front and ensure the rotation of the saucer portion 22, a metal that becomes a weight by insert molding is built in at an appropriate position, or a partially thickened portion. Or a weight may be added from the outside. For example, a weight may be provided at the front end edge portion of the saucer portion 22, or the periphery of the front end edge portion may be formed thicker than the other portions. The guide groove 24 is a groove through which the claw portion 26 passes, and defines a range in which the roll material tray 20 can freely rotate. The guide groove 24 is formed in a wide range so that the roll material tray 20 can be rotated further than the position where the tray portion 22 is suspended from the roll material support shaft 5 and stabilized by its own weight.

The roll material tray 20 is rotatably supported by passing the roll material support shaft 5 through the hole 23 of the arm portion 21 and hooking it on the roll material support shaft 5. Therefore, by setting the position of the center of gravity of the flap receiver 7 on the front side of the vertical line passing through the position where the edge of the hole 23 and the roll material support shaft 5 come into contact with each other, the position of the center of gravity between the arm portion 21 and the holder body 4 is set. When the restraint is released, the roll material saucer 20 rotates due to its own weight, and the saucer portion 22 moves downward and is supported so as to be suspended.

Here, in the case of the present embodiment, the claw portion 26 and the roll material support shaft 5 are provided with the roll material support shaft 5 and the claw portion 26 at the tip of, for example, an L-shaped resin plate, and are spring-loaded by the elasticity of the entire resin plate. Although it is configured to give properties, if the spring force is insufficient to lock it securely with only the resin plate, a coil spring or the like is incorporated in the holder body 4, and the holder body 4 has a built-in spring structure or the like. It may be provided so that it can appear and disappear inward from the side surface member 3 of the above. Further, in the present embodiment, the arm portion 21 is formed in a disk shape having a hole 23 in which the roll material support shaft 5 is fitted in the center, but the arm portion 21 does not have to be in the disk shape and supports the saucer portion 22. If it is obtained, for example, a fan-shaped plate may be used, and in some cases, a V-shaped or I-shaped rod may be used.

In the present embodiment, the holder body 4 is provided with a locking claw 26, and the arm portion 21 is provided with a locking hole 25 and a guide groove 24, respectively, but the present invention is not particularly limited to this, and the arm is not limited to this. A locking mechanism may be provided between the arm portion 21 and the holder body 4 by utilizing the elastic force or structural elastic force of the material itself between the portion 21 and the holder body 4. For example, although not shown, hemispherical protrusions are formed on the arm portion 21 or the holder body 4 side, while hemispherical holes or through holes are formed on the holder body 4 side or the arm portion 21 to create irregularities. The roll material tray 20 can be fixed to the holder body 4 when fitted. In this case, the arm portion 21 enables rotation and slides on the opposite surface on the holder body 4 side by temporarily elastically deforming when it is detached from or fitted into the hole or through hole of the hemispherical protrusion. Make it possible. In this case, the arc-shaped guide groove 24 is not required.

Here, the roll material tray 20 is located on the front side of the vertical shaft passing through the position where the edge of the hole 23 at the center of the arm portion 21 and the roll material support shaft 5 come into contact with each other (in FIG. 17, the roll material support shaft). The fixed position of the arm portion 21 to the holder body 4 is set so that the center of gravity is arranged at the position of the first quadrant when the XY coordinate plane passing through the center of 5 is set).

According to the roll holder configured as described above, when the roll material 1 is replaced, the core of the roll material 1 remaining on the roll material support shaft 5 is lifted and the roll material support shaft 5 is moved to the side member 3 of the holder body 4. If the lock claw 26 is removed while being displaced outward in the axial direction so as to be pushed inward, the lock claw 26 is also disengaged from the lock hole 25 of the roll material tray 20 and the lock of the roll material tray 20 to the holder body 4 is released. As a result, the roll material tray 20 rotates toward the front side around the roll material support shaft 5 due to its own weight, and the tray portion 22 moves to the replacement position (position in FIG. 16). At this time, since the roll material tray 20 is supported so as to be hooked on the roll material support shaft 5, the center of gravity is settled at a position where the center of gravity is on the vertical shaft passing through the center of the roll material support shaft 5.

On the other hand, in the case of the present embodiment, the guide groove 24 provided in the arm portion 21 is formed longer so as to have a room for the saucer portion 22 to rotate further to the back side than the position where the saucer portion 22 is settled by its own weight. Therefore, when the roll material 1 is attached between the roll material support shafts 5, the saucer portion 22 can be tilted so as to lower the front edge to, for example, the lowest position by pushing the saucer portion 22 further to the back side. .. As a result, the saucer portion 22 does not interfere with the insertion of the roll material 1.

Therefore, by inserting the roll material 1 between the roll material support shafts 5, it is fitted into the central hollow portion 1c and supported rotatably. Then, with the left and right roll material support shafts 5 inserted into the central cavity 1c of the roll material body 1a, the roll material body 1a is placed on the saucer portion 22 and temporarily placed. At this time, if the roll material 1 is placed on the tray portion 22 so that the portion pulled out from the roll material main body 1a hangs down toward the front side, the roll material tray 20 rotates toward the front side (counterclockwise rotation in FIG. 16). By rotating in the direction), the portion pulled out from the roll material main body 1a, that is, the uncut portion 1b rotates while being wound around the outer surface 28 of the saucer portion 22. Then, the uncut portion 1b is wound up while being sandwiched between the outer surface 28 of the saucer portion 22 and the flap 6. When the upper use position is reached, the lock claw 26 and the lock hole 25 are engaged with each other, and the saucer portion 22 is set in a fixed position (state of FIG. 17). As a result, the tip end portion of the roll material 1 is pulled out to the front side in a state of being sandwiched between the outer surface 28 of the saucer portion 22 and the flap 6, and is further to the front side of the outer surface 28 of the saucer portion 22. It is placed on the portion corresponding to the uncut receiving portion 10.

That is, with the tip of the roll material fully pulled out, it is placed on the saucer portion 22 (that is, the inner surface 27), and the roll material saucer 20 is rotated toward the front side (rotated in the counterclockwise rotation direction in FIG. 16). Only by itself, the drawer portion drawn out from the roll material main body can be placed on the uncut receiver 10 in a state of being sandwiched between the flap 6 and the flap receiver 7.

In the case of the roll holder of the embodiment shown in FIGS. 1 to 14, when the roll material 1 is replaced (attached), the flap 6 is turned over and then the tip portion of the roll material 1 is picked to form the flap receiver 7 and the holder body. It is necessary to pull out from the gap between the back member 2 and the back member 2. In this case, if the gap for pulling out the tip of the roll material is narrow, the work of pulling out the tip portion of the roll material 1 is troublesome, and if the tip of the roll material 1 falls into the above-mentioned gap, it takes time and effort to start over. Therefore, although the above-mentioned gap must be widened, there is a problem that the size of the holder body is inevitably increased.

On the other hand, in the case of the roll holder of the present embodiment, the roll material 1 is passed through the roll material support shaft 5, then placed on the saucer portion 22 of the roll material saucer 20, and the tip side is pulled out to the front side of the saucer portion 22. The roll material can be set in the holder body 4 in a state where the uncut portion 1b is pulled out from between the flap receiver 7 and the flap 6 simply by rotating the roll material tray 20 to the position of use after hanging the roll material tray 20 on the holder body 4. Therefore, the roll holder can be made compact without impairing the operability when the roll material is attached.

The roll material tray 20 of the present embodiment is provided so as to be rotatable with respect to the holder body around the roll material support shaft 5 by sharing the roll material support shaft 5 to which the roll material 1 is attached as a rotation shaft. The rotation support is not particularly limited to this, and a dedicated rotation shaft (including a boss or the like) separate from the roll material support shaft 5 may be provided for rotation support.

18 to 24 show still other embodiments. The roll material holder according to this embodiment is provided with a flap 6 and a flap receiver 7 under the roll material 1 and a blade 9 at the tip of the flap 6. Unless otherwise specified, the functions and structures of the flap 6, the flap receiver 7, and the blade 9 are the same as those in the above-described embodiment, and the roll material 1 can be easily attached and cut with one hand. Is.

In the roll material holder of this embodiment, the tip of the roll material 1 is taken out (in other words, the uncut portion 1b is pulled out) from the position on the back side of the holder, that is, the uncut portion of the roll material 1 is taken out. It is preferable that 1b hangs down not on the front side but on the back side. Of course, it is also possible to take out the tip from the front side of the roll material body 1a, detour it to the back side, and then pass it between the flap 6 and the flap receiver 7, but the detoured portion becomes loose and becomes resistance. There is a risk that it will not be taken out well or that it will hang down in front of the flap 6.

Here, providing the flap 6 and the flap receiver 7 under the roll material 1 means that the flap 6 and the flap receiver 7 are arranged above the roll material 1 supported by the roll support rod 5 as described above. In the comparison of, it means that it is simply arranged below the roll material 1, not that it is arranged at a specific position, and at least the flap 6 is supported by the roll support rod 5. It means that it is arranged at a position that does not hinder the pulling out of the uncut portion 1b from the roll material main body 1a. Further, assuming that the holder body 4 is made compact, it is divided into a vertical line in contact with the outer peripheral surface on the front side of the roll material body 1a supported by the roll support shaft 5 and a horizontal line passing through the center of the roll material body 1a. It is preferable that the flap receiver 7 is arranged in the area to be formed and outside the roll material body 1a, and in order to make both the height direction and the depth direction more compact, the flap rotation shaft 6a is also provided. It is preferable to arrange the material in the above region and outside the roll material body 1a.

That is, in the present embodiment, providing the flap 6 and the flap receiver 7 under the roll material 1 means that the uncut portion 1b is picked up by the finger 40 and inserted into the gap between the flap 6 and the flap receiver 7. When the rear part of the flap 6 is lifted to a certain degree (assumed to be about 2 cm), the lifting height (or horizontal movement amount) of the roll material 1 by the flap 6 is at least the central cavity 1c of the roll material 1 and the roll support shaft. It means that it is arranged at a position within the movement range allowed as a range in which it does not fall off from 5. For example, in the embodiment of FIG. 18, the flap 6 and the flap receiver 7 are installed at a position below the horizontal line in contact with the lower end (lower part of the outer peripheral portion) of the roll material main body 1a supported by the roll support shaft 5. However, the present invention is not particularly limited to this, and the holder body 4 is made compact, the uncut portion 1b is pulled out smoothly, and the finger between the flap 6 and the flap receiver 7 is shown. From the viewpoint of ensuring a minimum gap for facilitating the insertion of the 40, it is preferable that the 40 is arranged at a position as close as possible to the roll material main body 1a but not in contact with the roll material main body 1a.

On the other hand, the flap 6 is basically preferably arranged horizontally, but is not particularly limited thereto. For example, although not shown, the flap receiver 7 may be arranged at a position lower than the flap rotation shaft 6a on the front side of the roll material 1 and tilted forward, or conversely, after the roll material 1. The flap receiver 7 may be arranged at a position higher than the flap rotation shaft 6a on the side, and the flap 6 side may be arranged so as to incline forward and downward (see FIG. 9). Also in this case, the flap 6 and the flap receiver 7 are arranged so as not to prevent the finger 40 from being inserted while being brought close to the roll material 1, that is, the rear end side of the flap 6 is pushed and the roll material is obliquely upward. A structure can be formed in which a gap into which the finger 40 tip is inserted can be formed between the flap 6 and the flap receiver 7 in a floating state.

In addition, when the uncut portion 1b is sandwiched between the roller-shaped shaft and the shaft, it is difficult for the shaft to bend or to secure the parallelism of the two axes in two dimensions of XY and XY. There is a possibility that the contact pressure becomes non-uniform, or the contacted portion becomes a point or a partial portion, so that the fixing at the time of cutting the paper becomes insufficient. On the other hand, according to the contact between the flap, which is a flat surface, and the shaft, if the parallelism is maintained at least in one dimension, the contact pressure becomes uniform and the contacted portion becomes the entire area (linear). Therefore, it is easy to make the paper sufficient for fixing at the time of cutting. Even so, if the contact area between the flap receiver 7 and the flap 6 is narrow and the flap 6 contacts only linearly, the force for sandwiching the uncut portion 1b may be weakened in some cases. For example, in the case of the flap receiver 7 of a round bar, when bending occurs, even if a force is applied to pull out the roll material 1 drawn out to the blade 9 at the tip of the flap 6, the flap 6 is used. Sufficient pinching force may not be obtained between the rear side and the flap receiver 7, and forward slip may occur. In order to prevent this, it is preferable to increase the frictional force of the blade 9 with respect to the roll material in terms of material, structure, and shape. For example, by adopting a blade made of a resin having high friction such as EVA resin, it is possible to increase the tension applied to the portion pulled out from the roll material body, thereby preventing the pulled out roll material from slipping forward if it slips. .. However, in the case of increasing the frictional force between the blade 9 and the roll material 1 to be pulled out in this way, after cutting out the required amount of the roll material, the hangnail at the tip edge of the uncut portion 1b is the "tip" of the blade. The problem that the uncut portion 1b does not hang down because it cannot be peeled off from the blade 9 due to being entangled in the portion or being pinched in the "crotch" portion is likely to occur.

In order to prevent this problem, for example, as shown in FIG. 21, the flap 6 is provided with a through hole 29 in the vicinity of the blade 9 into which a finger 40 can be inserted in order to pierce and remove the uncut portion 1b attached to the blade 9. Therefore, it is preferable to promote the peeling of the uncut portion 1b and the blade 9. In the case of the present embodiment, the hole 29 is a plurality of perfect circles having a size in which the finger 40 can be inserted, but the shape is not particularly limited, and an ellipse, an oval hole, or a rectangle can be formed as long as the finger 40 can be inserted. It may be a hole, a hole of various shapes such as a triangle, a polygonal shape having a pentagon or more, or a non-circular shape. Further, the number of holes 29 does not have to be plural, and may be one.

Further, the means for promoting the peeling of the uncut portion 1b and the blade 9 is not limited to the above-mentioned through hole 29. For example, as shown in FIG. 22, when the drawn roll material is applied to the blade 9 to cut the roll. The peeling flap 32 is rotated so as to be lifted by the material 1, and after being separated, the tip side close to the blade 9 is lowered by the rotation due to its own weight to automatically separate the tip edge of the uncut portion 1b attached to the blade 9. You may use it. The peeling flap 30 is separated from the flap 6 by rotation by its own weight about the rotation shaft 31 and is separated from the flap 6 and receives the flap 6 and the flap on the uncut portion 1b drawn out from the roll material main body 1a, for example. The portion of the roll material that has passed between the roll material and the roll material and is pulled out from the main body of the roll material (the uncut portion: referred to as the uncut portion 1b) is peeled from the blade 9.

In the case of the present embodiment, the peeling flap 30 is rotatably attached to the flap 6 around the peeling flap rotating shaft 31 set between the flap rotating shaft 6a and the flap receiving 7 shaft. , It is provided so that it rotates so that the tip side hangs down due to its own weight. The peeling flap 30 may be, for example, a straight flat plate, but is preferably a plate curved around an axis parallel to the rotation shaft 31 for the peeling flap, and prevents the uncut portion 1b from hitting the blade 9. The structure should be such that there is no such thing. The peeling flap 30 has a structure in which the peeling flap 30 freely rotates around a rotating shaft 31 arranged between the blade 9 at the tip of the flap 6 and the flap rotating shaft 6a until it hits the stopper 32, and the tip side is lowered. When the portion pulled out from the blade 9 is applied to the blade 9 and cut off, the toilet paper is pulled up so that the tip side approaches the blade 9 and fits inside the blade 9 with the rotation shaft 31 as the center. At this time, when the uncut portion 1b drawn out from the roll material main body 1a is addressed to the blade 9 and separated, it is retracted so as not to interfere with it. Then, the rotation of the peeling flap 30 due to its own weight, that is, the descent on the tip end side of the peeling flap 30, is a stronger force than the uncut portion 1b adhering to the blade 9, so that the end of the uncut portion 1b attached to the blade 9 Is automatically disconnected.

Further, the blade 9 has, for example, a portion having low friction and a portion having high friction, the friction on the tip side of the blade 9 is high, the friction on the proximal end side is low, and the width on the proximal end side is larger than that on the distal end side. It is preferable to have a wide shape. For example, as shown in FIG. 23, it may be composed of a spire-shaped blade 9 including a tip portion 35 including a conical tip 33 and a conical base 34, and a cylindrical base 36. In this case, the roll material 1 is pierced, torn and separated by the spire-shaped blade 9 pierced into the uncut portion 1b of the roll material 1.

Further, the blade 9 is formed or coated with a material having high friction (that is, a soft material) such as EVA (ethylene-vinyl acetate copolymer resin) on the tip side of the tip portion 35, that is, the conical tip 33, and other The portion, that is, the conical base 34 and the cylindrical base 36, is made of a material having low friction (that is, a hard material) such as vinyl chloride or polyacetal. As a result, it is possible to achieve both good bite when pressing the cut-out portion 1b of the roll material and easy separation of the uncut portion 1b after cutting, and to promote peeling of the uncut portion 1b attached to the blade 9. it can. The blade 9 is not limited to the one formed integrally with the flap 6, and the blade 9 is formed into a saw blade shape with a soft resin such as EVA resin (ethylene / vinyl acetate copolymer resin) formed separately. The formed separate parts may be fixed to the flap 6 by adhesion or welding.

Further, the distance between the blades 9 and the blade 9 (width W1) is expressed as the diameter D1 of the cylindrical portion of the blade 9 (the blade 9 of the present embodiment has a spire shape and is therefore expressed as a diameter, but in the case of a saw blade shape. The width is about the same as the width), making it difficult for the cut end to be clogged. In order to prevent clogging of the cut end, it is desirable that the waist circumference of the blade 9 is the same from the intermediate portion to the base of the blade 9, that is, it is cylindrical.

Regarding the blade 9, the coefficient of friction is increased only on the front surface or a part of the blade edge within the range that fits in the body position portion shorter than the root portion, and the good bite when pressing the cutout portion 1b of the roll material and the cutting after cutting. It is preferable that the remaining portion 1b is easily separated from the blade and the peeling of the uncut portion 1b adhering to the blade 9 is promoted. In this case, the edge of the portion clogged between the blades 9 of the uncut portion 1b becomes a semicircle having a columnar shape approximately the same as the diameter D1 of the base 36 having a small friction, and the diameter of the conical tip 33 having a large friction. Since it has a larger gap than D2 and is easy to pull out, it will not get caught. Therefore, at the same time that the roll material 1 is separated, the uncut portion 1b hangs down due to free fall.

Further, even if the blade 9 is formed of a soft material as in the above-described embodiment, if the blade 9 is exposed to the front surface, some people may feel a sense of fear, or the blade may be caught and scratched. It is also possible to bear. Therefore, in order to eliminate this risk, it is preferable to project the blade only when the roll material 1 is pulled out and cut. For example, as shown in FIG. 24, the blade 9 is attached to a rotating body 37 having an eccentric center of gravity provided at the tip of the flap 6, and the rotating body 37 rotates together with the roll material 1 when the roll material 1 is pulled out. The roll material 1 is separated while the blade 9 projects on the moving locus of the roll material 1 and is fixed by the stopper 39 provided between the rotating body 37 and the flap 6, while the rotating body 37 is separated after the separation. It is preferable that the roll material 1 is automatically retracted from the movement locus by moving the center of gravity of the roll material 1. As a result, the risk that the blade 9 is exposed can be eliminated. In the present embodiment, the rotation shaft 6a of the flap 6 also serves as the rotation center of the rotating body 37. Further, reference numeral 38 in the figure indicates a region of a biased portion.

In the case of the present embodiment, the flap 6 is formed in a flat plate shape as a whole, but is not particularly limited to this. For example, although not shown, the region on the front side of the flap shaft 6a faces downward. It may be curved. In this case, the blade 9 formed on the tip edge of the flap 6 faces downward, making it difficult for the user to see, and the fear and anxiety about the blade 9 can be alleviated. Even if the blade is safe, there are many people who feel the psychological fear and discomfort of touching the blade, and many who show rejection of the blade protruding toward the front. This is preferable as a consideration for such users. Further, it is possible to eliminate the escape (slip) when separating the portion pulled out from the roll material main body 1a so that the force can be easily applied at a right angle and can be cut with a light force.

According to the roll material holder of the present embodiment configured as described above, the finger 40 enters the rear end side of the flap 6 from below in a state where the uncut portion 1b hanging from the back side of the roll material main body 1a is picked up. It is possible to complete the mounting of the uncut portion 1b of the roll material by only one series of operations of pushing the uncut portion 1b into the gap between the flap 6 and the flap receiver 7 and pulling out only the finger 40 while pushing up about 2 cm, for example. it can.

In the case of the examples of FIGS. 1 to 14, the setting work of the roll material 1 on the holder body 4 is as follows: 1) Rotate the flap toward the front by about 270 degrees, and 2) Flap the tip of the uncut portion 1b with the flap receiver 7. Three steps are required: inserting into the gap between the flap 6 and 3) rotating the flap 6 by about 270 degrees in the opposite direction to the original position. Moreover, in order to smoothly shift to the work of passing the uncut portion 1b through the gap between the flap 6 and the flap receiver 7, when the roll material 1 is set on the roll material support shaft 5, the outer peripheral portion of the roll material 1 is set. It must be set so that the take-out position of the roll material 1, that is, the tip of the uncut portion 1b is located in a narrow range near the upper apex (the highest point on the outer peripheral portion in the height direction).

On the other hand, in the case of the present embodiment in which the flap 6 and the flap receiver 7 are arranged under the roll material 1, the setting work of the roll material on the holder main body 4 involves pointing the uncut portion 1b of the hanging roll material to the finger 40. It can be completed by just picking it up with a finger and pushing it up to the front side while pushing up the rear end side of the flap, and the procedure of setting the roll material on the holder body 4 can be simplified. Further, when the roll material 1 is set on the roll material support shaft 5, if the tip side of the roll material 1 is extended by about 20 to 30 cm in advance, the roll material support shaft 5 can be set at the tip position. Even if the roll material is attached without wearing it, the part pulled out from the roll material body is already in a state of hanging behind the flap 6 and the flap receiver 7, so the tip of the flap 6 and the flap receiver 7 are picked up. It is very easy to pass between.

In order to pick the uncut portion 1b of the roll material 1, it is necessary to provide a hanging portion of, for example, about 5 cm. Therefore, as shown in FIGS. 1 to 14, when the flap 6 is provided above the roll material support shaft 5, the flap 6 is provided at least 5 cm or more above the roll material main body 1a, or It is necessary to project the flap 6 to the front side of the roll material body 1a so that the position where the uncut portion 1b sandwiched between the flap 6 and the flap receiver 7 hangs down does not cover the roll material body 1a. This hinders the compactness of the holder body 4 by that amount. On the other hand, in the case of the present embodiment, the flap 6 can be provided immediately below the roll material body 1a, and it is not necessary to project the flap 6 toward the front side of the roll material body 1a. Allows for compactness. Since the space under the flap 6 is outside the holder body 4, there is no restriction on the hanging of the uncut portion 1b of the rolled material pulled out, and even if it hangs down significantly, it can be used without any problem in use.

Further, when the flap 6 is on the roll material 1, the uncut portion 1b is divided into the flap 6 and the flap receiver 7 in a state where the flap 6 is turned halfway so as to stand up without being rotated about 270 degrees toward the front side. If you try to insert it into the gap between the two, the gap between the flap receiver 7 and the flap receiver 7 will be hidden behind the rising flap 6 and it will be a blind spot. Therefore, the roll material is attached with the posture tilted and the head moved sideways. It is necessary to do the work, and the work is difficult and time-consuming. However, in the case of the roll material holder of the present embodiment, the work is only to push the uncut portion 1b into the gap between the flap receiver 7 while lifting the rear end of the flap 6 to the extent that the finger 40 tip can be inserted, so that the shadow of the flap is hidden. There is no problem that it becomes difficult to work, such as hiding in the blind spot, and there is no need to set the tip of the roll material.

Further, if the flap 6 is on the roll material 1, the blade 9 is present at a position closer to the user's line of sight, and some people may feel psychological disgust, fear, or oppression. There is, and various measures are required to eliminate this. On the other hand, when the flap 6 is installed under the roll material 1, since the blade 9 moves away from the user's line of sight, it is less likely to give a psychological disgust, fear, oppression, etc. It eliminates the need for various measures to eliminate it.

The above-described embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be performed without departing from the gist of the present invention. For example, in the above-described embodiment, the roll material includes toilet paper having a central cavity as an example, but the present invention is not particularly limited to this, and a paper product wound into a roll or a cut made of polyolefin is used. Supplies (consumable materials) For example, roll-shaped film packaging structure (polyethylene bag is rolled into a roll and can be cut out one by one from the perforation, and is generally also called a roll-poly bag), kitchen paper. Needless to say, Saran wrap (registered trademark), aluminum wheels, plastic bags, etc. may be used.

Further, in the above-described embodiment, the roll material holder having a structure in which the roll material 1 is inserted from below, above, or from the front side with respect to the holder body 4 composed of the back surface member 2 orthogonal to each other and the left and right side surface members 3. The explanation is mainly given by giving an example, but the present invention is not particularly limited to this, and for example, the roll material support shaft (core rod), the flap support shaft, and the flap that stand upright with respect to the frame member attached to the structure, wall surface, or the like. And cantilever are provided respectively, and the roll material may be inserted from the side to be set on the roll material support shaft. For example, although not shown, the roll-shaped film packaging structure described above is placed between a horizontal core rod vertically arranged on the wall surface and a tubular holder body that surrounds the horizontal core rod and stores the roll material. It may be stored and pulled out from between the flap provided in the take-out portion of the tubular holder body and the flap receiver as much as the polyethylene bag is used.

Further, although not shown, the flap receiver 7 may have a structure provided with a passage space expansion mechanism capable of expanding the space between the flap receiver 7 and the flap shaft 6a by pushing down, for example, when passing the tip of the roll material. good. In this case, for example, the flap receiver 7 is supported by a relatively weak spring, and the flap receiver 7 functions to be pressed against the back side of the flap by the spring force unless a force for pushing down is applied by a finger 40 or the like. At the same time, when the roll material 1 is hooked on the tip of the flap 6 and a rotational force is applied to the flap 6, the paper is sandwiched while pushing down the flap receiver 7, so that an excessive force does not work. It may sink when the force for pushing down the flap receiver 7 is relatively strong, so that an excessive force does not act on the tip portion sandwiched between the flap 6 and the flap receiver 7. In the case of the flap receiver 7 with a passage space expansion mechanism, when the tip portion is pulled out from the roll material and passed between the flap and the flap receiver 7, the flap 6 and the flap receiver 7 sink due to the rotation of the flap 6 and the flap receiver 7. Since a wide space / gap is formed between the vehicle and the tip portion 7, the work of pulling out the tip portion, that is, the setting of the roll material can be easily performed.

Further, in the case of the above-described embodiment, the flap 6 is formed in a flat plate shape, for example, but is not particularly limited to this, and at least the flap tip edge portion pressed against the roll material to be cut off and the flap tip edge portion. It suffices that the trailing edge portion that sandwiches the uncut portion 1b between the flap receiver 7 and the flap receiver 7 has a shape that does not damage the pull-out portion of the roll material and has sufficient rigidity. The structure is not particularly required to have a flat surface or a curved surface. Therefore, for example, from the viewpoint of weight reduction, it is possible to adopt a frame having a hollow structure such as a lattice structure.

Further, in the above-described embodiment, the flap 6 has a short length, but the flap 6 is not particularly limited to this. In some cases, as shown in FIG. 8, the flap 6 may be extended in the depth direction to the vicinity of the back member 2 so as to also function as the upper lid of the holder body 4. In this case, the space above the roll material main body 1a can be shielded without increasing the number of parts to protect the roll material main body 1a from intrusion of dust and droplets of water droplets. In the case of the flap 6, for example, by using a lightweight material such as polyolefin, the operation when passing the portion drawn out from the roll material main body 1a through the gap between the flap shaft 6a and the flap receiver 7 becomes easy.

Further, the relationship between the contact portion 11 between the flap 6 and the flap receiver 7 and the flap shaft (fulcrum) 6a is directly linked to the improvement of sharpness by ensuring parallelism. Therefore, it is effective to integrate the flap receiver 7 and the bearing of the flap shaft (fulcrum) 6a. For example, as shown in FIG. 11, the flap receiver 7 having the bracket 12 may be attached by using the flap shaft 6a. Specifically, both side edges of the side (uncut receiving portion 10) on the front side of the contact portion (straight line passing through the bending point) 11 in contact with the flap 6 of the flap receiver 7 made of a plate material bent in a chevron shape are formed. The bracket 12 may be raised to form a bracket 12, and the bracket 12 may be provided with a hole 13 for passing the flap shaft 6a, and the flap receiver 7 may be attached to the holder body 4 using the flap shaft 6a. In this case, since the straight line (flap shaft) connecting the holes 13 through which the flap shaft 6a penetrates and the contact portion 11 are always arranged in parallel, between the flap shaft (fulcrum) 6a and the flap receiver (point of action) 7. It is easy to identify the position and secure parallelism.

Further, in the above-described embodiment, an example applied to the toilet paper holder has been described, but the present invention is not particularly limited to this, and for example, a product using a cut-out material made of polyolefin, which is wound into a roll, for example. It is also possible to target a roll-shaped film packaging structure (a polyethylene bag in which the polyethylene bag is rolled and can be cut one by one from the perforation).

Further, in the above-described embodiment, the flap 6 sandwiches the tip portion of the roll material by rotation such that the flap 6 is pressed against the flap receiver 7 from above by gravity (for example, rotation in the clockwise rotation direction in FIG. 1). However, this is not particularly limited to the horizontal installation method, and when the vertical installation method is used in which the flap shaft 6a is arranged in the vertical direction, the urging due to its own weight disappears, but a large frictional force is generated on the side surface of the roll material at the bottom. Since it is generated, the pressing force that has been urged to the flap by its own weight for the purpose of preventing the reverse rotation of the roll material becomes unnecessary, and thus does not hinder the implementation. Further, in the horizontal installation method of the above-described embodiment, the flap shaft 6a and the center of gravity of the flap 6 can be rotated by the holder body 4 so that the flap 6 is always urged toward the flap receiver 7 by its own weight. However, in some cases, the rotational force may be constantly urged in one direction by applying a spring force or the like.
